Embodiment 1

[0052] The following tests were carried out on the distribution uniformity of biomass graphene:

[0053] Composites of PC and ABS are used as polymer materials and biomass graphene with a particle size of less than 50nm in different contents to be composited. The timing of adding biomass graphene is melting, that is, adding biomass graphite when the polymer material is melted. Alkene, and stirred to mix, and then injection molding, prepared into a mobile phone case. The prepared material was observed by electron microscope and far-infrared test method to identify whether the distribution of biomass graphene was uniform. The specific experimental parameters and results are shown in Table 1.

[0054] Table 1 Distribution uniformity of different biomass graphene content in the material

[0055]

[0056] During the test, it was found that when the content of biomass graphene was higher than 10wt%, the distribution of biomass graphene in the prepared mobile phone case was obvi...

Embodiment 2

[0062] Radiation wavelength test of wireless communication equipment in different states

[0063] The compound of PC and ABS is used as the polymer material, and the biomass graphene with different content is prepared by injection molding method to prepare the 4G iPhone 6 mobile phone protective case (the mobile phone protective case does not cover the mobile phone antenna). The thickness of the used biomass graphene is below 50nm, and the particle size of the added biomass graphene is below 50nm. Using an electromagnetic radiation detector to detect mobile phone protective cases with different biomass graphene content installed on the same mobile phone under the 3G network state, and other conditions are the same, observe the signal strength of the mobile phone in the call state and standby state, and measure its SAR value (Specific absorption rate), as shown in Table 2 below. Specifically, the content of biomass graphene and the radiation wavelength of the mobile phone posi...

Embodiment 3

[0075] According to the mobile phone protective case prepared by the method of Example 2, antibacterial performance is detected, as follows:

[0076] According to GB / T 31402-2015 "Test Method for Antibacterial Performance of Plastics and Plastic Surfaces", the bacteriostasis of the mobile phone protective case prepared in Table 2 was measured. The types of bacteria tested for bacteriostasis include Escherichia coli and Staphylococcus aureus. The results are shown in Table 3.

[0077] Table 3 The antibacterial rate of mobile phone protective shells with different biomass graphene content

[0078]

[0079] As can be seen from Table 3, the mobile phone protective case provided by the present invention has significant bacteriostasis effect, and along with the increase of biomass graphene content, bacteriostasis performance promotes gradually, and when more than 0.1wt%, bacteriostasis performance all reaches more than 80%; when it is more than 1wt%, the antibacterial performanc...

Abstract

The invention relates to the field of communication materials, in particular, relates to the application of biomass graphene in the wireless communication equipment shell. The invention aims to provide the application of biomass graphene in radiation protection products, especially in the application of the shell of wireless communication equipment. Experiments show that the products made of composite products of the biomass graphene and high polymer materials can absorb the electromagnetic waves with longer wavelength generated by wireless communication devices, for example, the 17-33cm electromagnetic waves can be translated into the electromagnetic waves in the 4-14[mu]m band to be emitted out as the far infrared form, therefore, the harm of the mobile phone electromagnetic wave to the human body is reduced. The invention benefits the human health and has antibacterial properties.

Description

technical field [0001] The invention relates to the field of communication materials, in particular, to the application of biomass graphene in the casing of wireless communication equipment. Background technique [0002] Radiation itself is a neutral term, which includes two types of radiation that are harmful to the human body and beneficial to the human body. Generally, far-infrared radiation is beneficial to the human body, while radiation in other bands has no such effect on the human body, and nuclear radiation is seriously harmful to human health. [0003] Among communication devices, mobile phones are closely related to people, and mobile phone radiation exists all the time. Radiation occurs when talking, sending and receiving text messages, connecting to the Internet, and so on. Electromagnetic radiation is the so-called radiation generated when mobile phones talk, send and receive text messages, and connect to the Internet. Although there is no scientific method i...
